IMPROVEMENT IN CAR-AXL BCXES.

Specification forming part of Letters Patent N0. SAVQ, dated March 4, 1873.

To all whom it may concern:

Be it known that I, STEPHEN Usrrcmof the City of Philadelphia and state of Pennsylvania, have invented certain Improvements in Lubricating Car-Journals, of which the following is a specification:

My invention relates to the combination of a division-plate with the sides of a journalbox in such a manner as to form a closed oilchamber below the journal, the edges of the plate being provided with packing to prevent any dust which may nd its way into the upper part of the box passing into the oilchamber. The plate is held in its position by means of legs, which rest upon the bottom plate of the box; or it may be supported by means of springs, or in any. other convenient manner.

Figure 1 is a longitudinal section of a journal-box, A, and parts in connection therewith. Fig. 2 is a cross-section at the line m x of Fig. 1. Fig. 3 is an isometrical view of the division-plate D.

Like letters in allthe figures indica-te the same parts. i

A is the journal-box, B the journalfand G the journal-bearing. D is a division-plate, which separates the lower part of the box from the upper part, to form a closed oil-chamber, E, free from any dust or dirt which may find its way into the upper part of the box. The plate has a continuous groove, a, around its'edge, into which packing b is inserted before the plate is brought into its position, to make the joints sufficiently tight to exclude the dust from the oil-chamber E. The groove may be dispensed with, if desired, by forcing the packing between the edges of the plate and the sides of the box, or it may be' made ot' thin sheet metal and forced into its place so as to make the joints sufficiently tight to exclude dust or dirt. The plate is provided with legs c c c c, which rest upon the bottom plate ot' the box A. Other modes of sustaining the plate in position may, however, if desired, be adopted. The upper side of the plate is made of trough form, as seen clearly in Fig. 3, so asto`retain any waste oil from the lubricating and distributing pads F F and G G. The pads FF rest upon the side elevations d d of the plate, lling up the space between it and the lower dat edges of the journal-bearing, and touch the periphery of the journal B for lubricating the same. The oil is supplied to the pads F F from the oil-chamber E by means of the wicks H H, as seen in Fig. 1, openings being formed by recessing the iront corners of the plate, as seen in Fig. 3. These openings may be somewhat larger than the wicks, to admit of the passage of air into the oil-chamber to press upon the surface of the oil, and facilitate the ow of the latter through the wicks; or the same object may be accomplished by means of a tube connected with the front end of the plate. The pads G G at the ends of the trough are of such form and size as to press gently against the periphery of the journal B, to exclude dust or dirt therefrom. They also connect with the longitudinal pads F F, so as to cause a reiiow of accumulated oil from the one in front of the line of motion of the journal to the one in the rear of the same, to keep up a perfect lubrication, in the manner set forth in my patents dated April 30, 1872, Nos. 126,349, 126,350, 126,351, and 126,352, and my patent dated J ulyv 26, 1872, No. 129,500.

1f desired, the plate D may be of circular form, concentric with the journal B, so as to take in pads G G,of equal thickness; or the end portions which support the pads may be of such form, and the middle part flat, as represented 5 or the trough form ofthe plate may altogether be dispensed with. In this case the pads may rest on the at surface of the plate by making the pads wide enough to ill up the space between them and the lower iiat edges of the journal-bearing.

The plate D may be removed from the box A, when necessary, to clean out the sediment which is deposited from the oil.

I is a plate which fills up the opening in the front end of the box, back of the cap-plate, (not shown in the drawing.) It has a groove around its edge, which is lilled with packing f to exclude any dust which may pass under the cap-plate. rEhe groove may be omitted, it' desired, and-the packing inserted around the square edge ofthe plate.

I claim as my invelntioii-l rlhe detachable division-plate D, provided with packing b, in combination with the jour nal-box A, substantially in the manner and for the purpose set forth.
